To all whom t may concern.'

Be it known that I, CHARLES E. MCGILL, a citizen of the United States, residin at Binghamton, county of Broome, and tate of New York, have invented certain new and useful Improvements in Spindle-Retainers, of which the following is a specication.

This'invention relates to attachments for retaining the spindles of spinning machines, or the like, to prevent them from being lifted from the bolster when removing a bobbin therefrom; and is particularly suited for use in connection with spindles whose holsters are resilient-ly held upon their supports.

The objects of this invention are to provide such a retainer which may be securely locked in holding position, which may be readily released and relocked without the use of any tool or implement andby a simple manipulation thereof, which is'durable and is inexpensive to manufacture, and which may be readily applied to existing Other objects of this invention will be scribed in the following 4specification and more Vparticularly pointed out in the anneXed claims. I

VThis invention will be best understood by reference to the accompanying drawing in which- Y Figure l is an elevation of a typical spin- 4dle'and its supporting structure with this invention applied thereto.;

Fig. 2 isa plan view of the parts shown by Fig. l showing the retainer in unlocked position; and f Fig. 3 is a plan view of the Vsupporting bracket and the retainer of Fig. 2, showing the depending stud of the bolster in ycross section,jthe retainer being locked in retainingV position.

Referring to Figs. 1 and 2, the spindle 21 carries the pulley 22 having an annular flange 23 atthe lower end thereof. Said spindle is journaled to the bolster 24, which bolster rests upon the retainer plate Said plate rests upon the supporting bracket 26 which bracket has an upwardly extending pin 27. i

A depending stud 28 extends from the un i 4der side of the bolster 24, through an opening provided therefor through the plate 25 and support. 26; and the lower end of said stud carries the nut 29, between the upper face of which nut and the under side of the support 26, the spring 3() is so applied as to resiliently draw the bolster 24 toward the support 26. A notch 31 is provided in the bolster 24 for receiving the pin, so that said pin 2 7 may serve to suitably limit relative rotativeY movement therebetween'.

An upturned projection 32 is carried by the plate 25, the free end'33 of said projec` tion being disposed substantially parallel to the main portion of the plate 25 and spaced slightly above the iange 23, so as to provide a suitable running clearance therefrom. Said end 33 is so formed that it may overlap a suitable portion of the flange` 23, and so that, when so overlapping said flange, said end may prevent the spindle 21 from being lifted from the bolster 24.

Referring now more particularly to Fig. 3, it will be seenthat the elongated openin 34 is so formed as to receive both the stu 28 and the pin 27; theend 35 of said opening being so positioned with relation to the end 33 of the projection 32 that, when said end rests against the stud 28,'such end 33 will overlie the flange 23 and will be separated from the pulley face 22 by a suitthe plate 25 may berotated around said stud so as to carry the ledge `36 outside of the pinA 27, and Vsaid plate 25 will be thereby locked againsttransverse movement thereof; and said slot 37 is so formed'that, when the plate 25 is so rotated' around thestud 28 as to presentsaid slot to the pin 27 saidplate 25 may be moved transverselyto an extent suiiicient to carry the end 33 out of the pathV of the flange 23, and will therefore permit the spindle 21 to belifted off from the bol- 100 ster 24.

In the use of this invention, the retainer plate 25 is normally positioned as shown in Figs. 1 and'3, said plate being locked against transverse movement by the engagement of the locking ledge 36 with thepin 27,` and being further held against movement relatively to the bolster 24 by the frictional engagement of the under side of said bolster with the upper side of said plate. The end from the bolster 24, the plate 25 should beA rotated clockwise until the slot 37 is presented to the pin 27, and the plate 25 should thereupon be moved transversely, to the position indicated by Fig. 2, thereby withdrawing the end 33 from the path of the flange 23.

lllhen it is desired tov again lock the spindle 21 in position upon the bolster' 2%, the plate 25 should be moved transversely until the end 35 ofthe opening 34 rests against the stud 28, and said plate should thereupon be rotated around said stud, in counterclockwise directionuntil the slot 37 is vwithdrawn from the Vpin 27.

Y It is evident that, should the pin 27 be carried by the bolster 24 (instead of by the bracket 26, as shown), such pin would neverthelessperform `its intended functions in an effective manner, and that, should such pin be entirely dispensed with, other features of this invention could nevertheless be advantageously employed, as the friction applied to the opposite sides of the plate 25 by the bolster 211 .and bracket 26 couild be relied upon for holding Ssaid plate against trans- -versemovement thereof. It is also evident that the functions of the pin 27 Amight be readily consolidated withthose of the stud 28, as will be well understood by those skilled in this art. g l j Y' Variousother changes may also be made in the number, form and arrangement of the parts shown without departing from the spiritof-this invention; and what l therefore claim and desire to secure by Letters Patent ofthe United. States of America is:

1. The combination of` a vertical spindle, a bolster upon which said spindle is journaled, a supporting member for said bolster, and a retainer for said'spindle frictionally held between said bolsterand said member.

2. The combination of a vertical spindle, a bolster `upon vlwhich said spindle is journaled, asupporting member for said bolster, a retainerfor `said spindle frictionally held Vbetween saidbolster and said member for movement into either an effective or an ineffective position with relation to said spindle, and means other than such frictional engagement for holding lsaid retainer'against movement from its effective to its ineffective position.

3. The combination of a vertical spindle, a bolster upon which said spindle is journaled, a jretainer for said spindle frictionally secured to said bolster for relative move- `ment around. and transversely to the axisY of said spindle, and such relative construction and-v arrangement of partsthat said retainer may be moved transversely to an effective or an ineffective position and so that said retainer may be rotated, while in its effective position, so as to permit or prevent transverse movement thereof.

4C. The combination with a vertical spindle having an annular flange adjacent to the lower end thereof, a bolster member upon which said spindle is journaled, and a bracket member for supporting said bolster,-of a plate frictionally held between said bolster andA said bracket and movable relatively thereto, and an upturned projection carried by said plate, the free end of said projection being adapted to overlap the upper face of said flange. f

5. The combination with a vert-ical spindle having an annular flange adjacent to the lower Vend thereof, a bolster member upon which said spindle is journaled and abracket member for supporting said bolster,-of a projection carried by one of and extending across the planes ofthe adjacent faces of said members, a plate frictionally held between said adjacent faces for movement Atherebetween transversely to the axis of said spindle and so formed that such transverse movement may carry a portion thereof into or out of the path of said flange, and such relative Vconstruction and arrangement of said plate and said projection that, while vsuch portion of said plate is in thefpath of plate having an opening ,therethrough for said stud, said plate being so formed that one portion .thereof providesa support for the lower face of said bolster and another portion thereof forms a lug normally disposed adjacent to said pulley face above vsaid lug, a support for said plate having` an opening therethrough for said stud, and a spring applied between said stud and the .lower side of saidsupport. Y v

7. The combination witha vertical spindle having an annularflange adjacentlto the lower end thereof, a bolster member upon which said spindle is journaled, and a bracket member for supporting such bolster,of an upwardly extending projection carried by said bracket in position-to engage the said bolster to prevent relative'movement therebetween, a retainer for (said spindle comprising a plate having a recess therethrough for receiving said projection, said recess being so formed with relation 'to said projection as to permit movement of said retainer transversely to or concentric with the axis of saidspindle,A such transverse` movement being arranged to govern the effectiveness of said retainer with relation to said spindle and such concentric movement being arranged to aiiord locking means for governing the transverse movement of said retainer from its effective to its ineffective position.

8. The combination of a vertical spindle having a pulley face carrying an annular flange, a bolster member upon which said spindle is journaled, a supporting bracket member for said bolster having an opening therethrough, a downwardly extending part carried by said bolster member andi, .extending through said bracket member, a spring for urging said members toward one another, a pin carried by said bracket member and so engaging said bolster member as to suitably limit rotative movement thereof with relation to said bracket member, and a plate frictionally held between said members and extending above said flange for limiting the movement thereof away from said bolster, said plate being recessed for said part and said pin so as to permit movement of said plate transversely to said spindle out of the path of the flange and so as to permitl rotation of said plate around Y said recess to a position where it will be looked against such transverse movement.

9. VAs an article of manufacture, an attachment for retaining a spindle comprising a plate adapted for insertion between a bolster and the support provided therefor, said plate having an elongated opening therethrough for a stud extending from such a bolster and having an extension for limiting movement of the spindle away Jfrom such bolster.

i0. As an article of manufacture, an attachment for retaining a spindle comprising a plate adapted for insertion between a bolster and the support provided therefor, said plate having an elongated opening therethrough for a stud and for a pin eX- tending from such a bolster, and having an extension for limiting movement of the spindle away from such a bolster, said opening being so formed as to permit transverse movement of said plate to effect release of the spindle when said plate is in a certain4 position with relation to such pin and to prevent such transverse movement when said plate is not in such relative position.

In witness whereof, I hereunto subscribe my name, this day of November, 1920. CHARLES E. MCGILL.
